How do you 'revive' your wooden grip's stippling?

I have a Pardini wooden grip that I have been using for years.  The stippling has become somewhat smooth and I wish to 'revive' it.  Normally, I use a small nail and hammer.  But I was wondering what other techniques people have used that may be more efficient than the hammer and mail method.  Thanks.

Randall Fung taught me to use a Dremel with a 191 ball head.   It blended in exactly.

Center punch and hammer

Both the nail and Dremel method:

I took a bunch of 4, 6 and 8-Penny finishing nails reshaped the points then cut the hammer end off and silver soldered them together in a bunch, about 3/8" diameter of them, making sure the points were level with each other.  Worked pretty good stayed sharp enough to do 2 wood grips.  Last time I used it I did a poly grip on an XDM by heating it up, used an old drill chuck to hold it.

It always depends on the stippling I'm trying to match. I prefer the tiny ball head bit in the dremel but have used a small drill bit as well as the hammer and punch method. I hold the grip in my lap and use a rapid tapping motion. I like Dave's gang punch idea!

a good electric engraver tool works great too

Thank you for all the suggestions.

I sharpen the end of a very small screw driver to a sharp point and go at the grip like a woodpecker on crack.

I wonder if an ice pick would work as well?  That is, after you use it to make your cocktail.

A scratch awl would be perfect.
